A Phase II Study Comparing Romiplostim with Observation for Chemotherapy-Induced Thrombocytopenia

Full Title

A Open Label Phase II Study for Chemotherapy Induced Thrombocytopenia


Chemotherapy drugs for cancer often reduce the levels of healthy blood cells in the body, such as platelets, which are necessary for blood clotting. When platelet counts fall below a certain level, it is called thrombocytopenia. Patients whose platelet counts fall below 100,000 cannot receive chemotherapy until the count comes back up. Treatment may be delayed or the chemotherapy dose reduced, lowering its effectiveness against the cancer.

In this study, researchers want to see if the drug romiplostim (Nplate) is effective for increasing platelet counts in patients with thrombocytopenia due to chemotherapy. Romiplostim boosts platelet counts and is already approved for treating thrombocytopenia due to other causes.

Researchers will determine if weekly romiplostim injections are more effective for raising platelet counts than waiting for them to rise on their own, and to see if romiplostim enables patients to receive at least two more cycles of chemotherapy without developing thrombocytopenia. Patients will be randomly assigned to receive romiplostim injections, or undergo observation with no treatment.


To be eligible for this study, patients must meet several criteria, including but not limited to the following:

  • Patients must have thrombocytopenia as a result of chemotherapy for a non-hematologic cancer.
  • At least 2 weeks must have passed since the last dose of chemotherapy and entry into the study.
  • Patients must be able to walk and do routine activities for more than half of their normal waking hours.
  • This study is open to patients age 18 and older.
